place of starting and for automatic spacing;

and the object is to construct a device that -will accomplish these results without in any way interfering with the working of a typewriter and by which the type-writer carriage can be sent back to the first position from any point without the necessity of going to the end of its beat. Other objects and advantages will be fully understood from the following description and claims when read in connection with the accompanying drawings.

Similar characters of reference indicate similar parts throughout the several views.

The device (shown in Fig. 1) maybe mounted in any suitable way, as by a hanger attached to frame A, or by uprights attached to Serial No. 637,593. (No model.)

the base-piece of the type-writer, or by cross pieces attached to the posts between the piece A and the base. A drum l3 is loosely mounted on a shaft Z), and a cord 0 is attached to this drum and to the carriage-frame at any suitable place on the left side, as to the hanger for rod D, the same rod to which the cord for advancing the carriage is attached. The cord C runs over pulley (Z and draws the carriage to the right by means hereinafter described. Cooperating clutch-drums E and E are mounted on shaft b. A spiral spring 0 is mounted on shaft 1) between the clutchdrums. Drum F is loosely mounted on shaft f and is provided with cogs G, which mesh with pinion G, which is mounted on shaft 1). Drum F contains a coiled spring H. (Shown in section in Fig.1.) One end of this spring is attached to the shaft f and the other end to the rim of drum F. This spring must be su perior to the spring which causes the advance of the type-writer carriage. Drum F may be locked to the shaft f by means of the ratchet J, which is rigidly mounted on shaft f, and the s pring-pressed pawl j, operated by spring j. Spring] and pawl j are attached to the hanger 4 or to some stationary support. These parts and the ratchet-wheel J may be on the inside or outside of the hanger. The drum B and face-clutch E are made integral with each other and are loosely mounted and have axial movement on the shaft 1). A groove is left between drum B and the eX- terior surface of clutch E for the yoke L. The cooperating parts of the clutch are thrown in mesh by means of the yoke L, provided with the arms Z and Z and with suitable connecting-levers. A disk K is loosely mounted on and has axial movement on the shaft 1) and is provided with lugs 7tand 7t and projections 11 and n. This disk does not revolve, being attached to prongs r r of the lever N. Arms Z and Z of the yoke L are attached to the projections n and n of the disk K. The characters r 1" indicate apertures for bolts to attach prongs or arms To" to disk K. The clutchdrum E has pairs of apertures R for the lugs 70 and 7t. Any movement of the disk K axially will move drum B and clutch E corre-.

spondingly. The clutch should begin to look before the lugs 7c and 7a are entirely withdrawn from the apertures R, and in unlocking R line spacing.

the lugs should begin to entertheaperturesR before the clutch'is entirely unlocked. The lugs 7c and 79 prevent the revolution of clutch E and pinion. G when unlocked Pinion G will prevent the revolution of drum F. The shaftp is arranged as the shafts for operating the type-levers are,and leversp arerigidly secured on the shaft 19. The button g has a stem whichis pivotally connected to one of the levers p, and the other lever 9 is pivotally connected to the link 7)", which is pivotally connected to the arm N. (See Figs. 3, 5, and 7.) Pressure on button qwill depress arm N and throw the clutch in mesh. At the same time lu s 7c and 7c are withdrawn from a ertures R in the clutch-drum E. This leaves clutch-drum E free to be driven by the tension of spring H. In rotating the clutchdrum E carries clutch-drum E with it, and

consequently drum B winds cord 0 on this drum, and consequently draws the carriage back to starting position. hen pressure is taken off of button q, the spiral spring 6 throws clutch out of mesh and at the same time forces the plugs 7.; and 70 into apertures R, and thus prevents spring II from losing all its tension. So in each operation just enough tension is used to bring the carriage back to starting position.

In moving the carriage back to starting position something is needed to accomplish the For accomplishing this the usual ratchet T is mounted on the end of the platen-roller, and means for rotating said roller are mounted on the frame of the typewriter. A rock-shaft S is mounted on the frame-piece S in suitable bearings. A linespacehandle T and a ratchet-lever T are mounted on this shaft. The ratchet-lever is provided with a finger M, pivotally mounted, therein. These parts stand normally in the position shown in Fig.10, the finger M resting against a shoulder M" on a stationary mounting P. A spring M is mounted in lever T and coiled around a pivot-bolt v1 and secured to said bolt by passing the end of the.

spring through said bolt. The bolt 2' is pivoted in the lever T, and the fingerMis mounted on the bolt t', and when the bolt turns the finger turns. The tension of the spring to uncoil itself actuates and causes finger M to engage ratchet T and turn same whenever the shaft S is rocked far enough to raise the lever T the requisite distance. The mounting P may be set at different positions to determine the number of spaces the finger M must move the ratchet T. The mounting may be set nearer or farther from the ratchet T. The handle S carries a lug 2, which is made to engage any desired cog in rack 1. The lug 2 is held in engagement with the rack 1 by means of a spring 3, mounted in handle S. As the finger M is moved away from the shoul der M the spring M causes the finger to turn enough to engage the ratchet T. The shouL der M" holds the finger M normally in the position shown in the drawings. The spacing is done automatically. It is only necessary to put something to trip space-handle T as the carriage is moved to the right. For this purpose a rod V is mounted on the type-writer frame. If for any reason a line-space handle is needed in front, an additional handle V maybe mounted on rock-shaft S at the front..

The handle T has a lug :0 integral therewith, which engages a lug 1 integral with the shaft S. hen the carriage moves back to starting position, the handle will strike the tripping-rod V. This will cause the handle to rock shaft S, and the spacing-lever T shoves upward to turn the platen-roller instead of downward, as in the ordinary type-Writer. In going to the left the handle will pass over the tripping-rod without rocking the shaft; but in going to the right the lug a: will engage the lug yand cause the handle T to rock the shaft S until the handle T passes over the tripping-rod V.

As the carriage will move back to starting position rapidly, at check will be necessary.

For this purpose an elastic buffer is provided.

This may be of rubber, or a pneumatic socket may be provided, which may be mounted so as to be struck by the marginal stop B. This stop will strike a piston R of a pneumatic cylinder as the carriage comes back to the starting position. I

The spring II may be wound by a key or a crank or by any other suitable instrument. In Fig. 7 is shown a crank j for winding the spring. This spring may be of any suitable length, and the longer it 'is the less often it would have to be rewound. The size of the pinion G and the size of the drum F, which is provided with the cogs G and which is inmesh With the. pinion G, will also aid in de-' termining how long the type-writer can be run without rewinding.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
